The Zincke-Suhl reaction is a special case of a Friedel-Crafts alkylation and was first described by Theodor Zincke and Suhl.
The classic example of this reaction is the conversion of p-cresol to a cyclohexadienone (with the aid of aluminium chloride as a catalyst and tetrachloromethane as a solvent). Melvin Newman, a scientist from the U.S. intensively studied the reaction in the 1950s and reported several improved procedures as well as mechanistic studies.
The reaction product is a starting material in the dienol benzene rearrangement.
Famous quotes containing the word reaction:
“Sole and self-commanded works,
Fears not undermining days,
Grows by decays,
And, by the famous might that lurks
In reaction and recoil,
Makes flames to freeze, and ice to boil.”
—Ralph Waldo Emerson (1803–1882)
